The testing device of the present invention includes an RF input for connecting to a subscriber network, which has been disconnected from a communication network, for receiving ingress RF signals leaked into the subscriber network from outside sources. The device includes a signal processor for scanning the RF signals for power levels at a plurality of frequencies, and generating power level signals based at least in part on the power levels. Ideally, the power levels are compared to a threshold power level representing an acceptable amount of ingress, and a pass/fail indicator is displayed based on whether the power levels exceed the threshold power level.
